Here are most of the references for my talk on electronic payment systems.
Time permitting, I should talk about <I>i</I>KP, anonymous credit cards,
untraceable cash, 
micropayments and finally CAFE. The papers for these are in "/u/ssinha/pub/elec_pay".

As is usual on the net, there is far too much information/junk around. So I am

contain anything useful.
